Sam Tunnicliffe commented on CASSANDRA-14206:
---------------------------------------------
Running the new dtests against 3.11 results in a bunch of failures at the
moment. Some are legit failures and some are problems with the tests. I've got
a branch where I'm pushing fixes to the test plumbing (including the attached
diff): https://github.com/beobal/cassandra-dtest/tree/14206
> Python 3 LooseVersion breaks compatibility with Python 2.7 LooseVersion

> In 2.7 it uses the cmp built-in to compare the list of version components
> which accepts comparisons of strings and integers. In python 3 it manually
> compares each using <, ==, and > which can fail if the the types don't match.
> Switch to using our own comparison function that preserves the old behavior.
